4179 Toutatis (1934 CT) is an elongated asteroid in the main asteroid belt, and is also a Mars and Earth crosser. It was first discovered on 10 February 1934, but was lost until is was again sighted on 4 January 1989 by Christian Pollas. It was named after a Celtic god.

Toutatis can approach Earth as close as 2.8 lunar distances, and approached as close as 4 LD in 2004. It has a 3:1 orbital resonance with Jupiter and near 1:4 resonance with Earth. This leads to a very chaotic behavior in its orbit which does not allow accurate predictions of its orbit far into the future. It has been classified as a potentially hazardous object.

Toutatis has been studied by radar a number of times and was visited by Chang'e 2 during a flyby on 13 December 2012.
